Wait, Give me a second to re-watch this, I'l edit this post in a second.
Okay so, I watched the second round closely, I noticed that he was waiting for someone to come, He could BARELY even see you coming from there, Once you came he shot's in a millisecond without a reload, Which is a sign of shotbot. There were also other sign's of shotbot, Such as the one when he turns and shoots you (you died).
So I guess that was my bad, I have to vote yes on Hakui.
Checking the other player now.
